- Page 6 Operation A. Starting Up 1. Before using the microscope, adjust the light intensity control (20) to minimum position. This should be repeated every time the microscope is switched on or off to prolong the use of the bulb. 2. Switch to position ON. (Fig. 4) 3.
- Page 7 E. Köehler illumination. The ideal level of illumination when all illumination elements are brought into proportion, basically, by the condenser and the field diaphragm. 1. Focus on a sample with the 10X objective (5).. 2. Close the field diaphragm (11) turning the ring situated on the illuminator (19), until it appears in the field of vision.
- Page 8 b. If air bubbles appear, they can be removed by moving the revolving nosepiece (3) slightly back and forth. c. After using the microscope, all parts that have come into contact with immersion oil must be cleaned. Using a soft cotton cloth lightly dampened with Xylene. If the 100X objective is not cleaned, oil could dry on the lens surface resulting in the view being blocked, and possible damage occurring.
